摘要： The present invention relates to a color imaging device which suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary part in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizontal direction is little and the false signal appears in a boundary part in the horizontal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the vertical direction.As a result, the moire phenomenon attributed to the false color signals can be conspicuously reduced.While embodiments of the present invention refer to color imaging devices which employ MOS type solid-state imaging devices, the invention is also applicable to an imaging device which employs CCDs and a color image pickup tube which separates colors by means of a mosaic color filter.

摘要： This invention relates to a solid-state imaging apparatus wherein photo signals are read out through MOS type FETs from photosensors such as photodiodes arrayed in two dimensions in large numbers, and consists in remarkably enhancing the signal-to-noise ratio of an output signal by reducing or eliminating noise components to mix into the photo signals.The analysis of the noise components has revealed the correlation in which the noise component in a certain polarity develops in the opposite polarity again after a period that is shorter than one horizontal scanning period by the duration of one horizontal scanning pulse. With note taken of the correlation, a solid-state imaging apparatus comprising a processing circuit which includes a delay circuit and an adder circuit and which cancels the noise is provided.

摘要： A color imaging apparatus having a plurality of image pickup tubes which pick up respective optical images of primary colors separated from one optical image includes a registration control circuit which operates to hold a picture of high quality at all times by controlling the registration of the images of the respective image pickup tubes on a real time basis during the operation of the camera. To this end a circuit detects those local image signals which satisfy predetermined requisites which are most favorable for use as reference signals to control the registration and these detected image signals are temporarily stored so as to be used for the registration operation. The most favorable requisites of the local image areas selected for registration control are (1) those having no movement, (2) those having a contour which is sharp and (3) those having a chroma which is low.
